For the first drawback can be overcome only through technology and perseverance. Using reasonable equipment and software, recorded course content can be display, speaker appearance, captions and background music led classroom rhythm once synthesis. You do not need to edit later, so that you can achieve the effect of recording that is broadcast.
In fact, this is the middle of the most difficult question is how to explain the results of the process of speaker psychological pressure, reduce slip of the tongue and NG shots. This question during the lectures is not obvious, but during the recording process you need to do it once is not easy.

Only with stupid way to solve this problem, it is ready "in the course of the recorded word for word transcript ," all the words to explain the design, courseware and in every eleven input screen actions can be. This will ensure that under no circumstances NG, do explain, screen events, letters to achieve the perfect unity.
While the text entry fee a little something, but compared to the lens processing NG is much more convenient. In particular, can explain an appropriate increase in speed, compression long course. With its speech-recognition software entry, can greatly improve the speed of entry editing text.
